Description
Technical field
The utility model relates to a kind of lost foam casting apparatus, especially relates to a kind of evaporative pattern and filters pouring device.
Background technology
Lost foam casting the paraffin similar to casting dimension shape or bubbles model is bondd to be combined into model cluster, after brushing refractory material is also dried, be embedded in vibration molding in drystone sand, pour into a mould under negative pressure, model is gasified, liquid metals occupies modal position, forms the casting method of foundry goods after solidifying cooling.Lost foam casting is the new technology of a kind of Near net shape, precise forming, and this technique is without the need to delivery, without die joint, without core, and thus foundry goods does not have overlap, burr and pattern draft, and decreases the scale error caused due to core combination.Surface roughness can reach Ra3.2 to 12,5um, and casting dimension accuracy can reach CT7 to 9, and allowance mostly is 1.5 to 2mm most, can greatly reduce the expense of machining, compare, can reduce a large amount of machining times with traditional molding sand casting method.
Lost foam casting cast, in cavity filling process by the impact of many factors, inevitably there are some impurity in molten steel, cause the product of casting can produce slag inclusion phenomenon to a certain degree, affect the quality of product.
Utility model content
The utility model object is to provide a kind of evaporative pattern and filters pouring device, inevitably there is slag inclusion phenomenon, affect the technical problems such as product quality to solve in existing evaporative pattern casting molten steel to exist in impurity, product.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of evaporative pattern filters pouring device, comprise sprue, the bottom of sprue is connected with the slag trap of taper, and the discharging side of slag trap is provided with ceramic filter block, and the exit side of ceramic filter block is connected with surge chamber, surge chamber bilateral symmetry is provided with cross gate, cross gate is symmetrically arranged with ingate, and ingate is connected with casting mold cavity, is provided with fibrous filter net between ingate and cross gate.
As preferably, described ceramic filter block is provided with the filter bores of Triangle-Profile, filter bores feed side diameter is 2mm, and filter bores exit side diameter is 3mm.
As preferably, described surge chamber, comprises the diversion section of inclination, and diversion section end is provided with the breeze way of arc, and breeze way end is provided with the flared section of inclination, and flared section end is connected with the outlet section of level.
As preferably, described ingate is arranged on the bottom of cross gate.
This evaporative pattern filters pouring device, and being provided with two-stage filter, is ceramic filter block and fibrous filter net respectively.Ceramic filter block has good hot operation intensity, the ability of thermal shock resistance and anti-metal liquid flow impact, there is high mechanical strength and resistance to mechanical impact capacity, effectively can reduce the turbulent flow pouring into a mould the molten metal brought, make to fill type reliable gently, the filter bores that ceramic filter block distributes makes it have larger metal flow rate, and flow rate is stablized.Some larger field trashes gather at slag trap place, and less field trash can be filtered by the filter opening that fibrous filter net is tiny.The utility model can improve in existing evaporative pattern casting molten steel and exists in impurity, product and often there is slag inclusion phenomenon, has good practical value.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the A direction view of Fig. 1;
Fig. 4 is the structural representation of surge chamber;
Fig. 5 is the structural representation of ceramic filter block;

Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Fig. 1 is structural representation of the present utility model, and Fig. 2 is the top view of Fig. 1, and Fig. 3 is the A direction view of Fig. 1, and Fig. 4 is the structural representation of surge chamber, and Fig. 5 is the structural representation of ceramic filter block, and Fig. 6 is the sectional view of Fig. 5.
As seen from the figure, this evaporative pattern filters pouring device, comprise sprue 5, the bottom of sprue 5 is connected with the slag trap 6 of taper, the discharging side of slag trap 6 is provided with ceramic filter block 7, and the exit side of ceramic filter block 7 is connected with surge chamber 4, and surge chamber 4 bilateral symmetry is provided with cross gate 1, cross gate 1 is symmetrically arranged with ingate 3, ingate 3 is arranged on the bottom of cross gate 1.Ingate 3 is connected with casting mold cavity, is provided with fibrous filter net 2 between ingate 3 and cross gate 1.
Ceramic filter block 7 is provided with the filter bores 71 of Triangle-Profile, filter bores 71 feed side diameter is 2mm, and filter bores 72 exit side diameter is 3mm.
Above-mentioned surge chamber 4, be provided with to surge chamber 4 bilateral symmetry the diversion section 41 of inclination, diversion section 41 end is provided with the breeze way 42 of arc, and breeze way 42 end is provided with the flared section 43 of inclination, and flared section 43 end is connected with the outlet section 44 of level.
Above-mentioned sprue 5, cross gate 1, ingate 3, surge chamber 4 are EPS material (polystyrene foam plastics).
This evaporative pattern filters pouring device, and being provided with two-stage filter, is ceramic filter block and fibrous filter net respectively.Ceramic filter block has good hot operation intensity, the ability of thermal shock resistance and anti-metal liquid flow impact, there is high mechanical strength and resistance to mechanical impact capacity, effectively can reduce the turbulent flow pouring into a mould the molten metal brought, make to fill type reliable gently, the filter bores that ceramic filter block distributes makes it have larger metal flow rate, and flow rate is stablized.Some larger field trashes gather at slag trap place, and less field trash can be filtered by the filter opening that fibrous filter net is tiny.
Molten iron is when sprue fills type to the junction of cross gate and surge chamber, flow velocity sharply reduces, pour into a mould the field trash brought into because of its proportion little, the upper end of slag trap is floated to rapidly after ceramic filter block filters, molten iron after filtration is flowing through ingate through cross gate, because ingate lays fibrous filter net (aperture is less), some tiny field trashes are unlikely to enter die cavity inside generation slag inclusion by floating to rapidly the upper end (ingate and cross gate have difference in height) of cross gate after filtration.Thus guarantee hot metal purifying.
Finally, it should be pointed out that above detailed description of the invention is only the more representational example of the utility model.Obviously, the utility model is not limited to above-mentioned detailed description of the invention, can also have many distortion.Every above detailed description of the invention is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection domain of the present utility model.
